IMPROVEMENT lN WA GON-BRAKES.

Specification forming part of Letters Patent No. 200,887, dated March 5, 1878; application filed December 26, 1876.

tion thereof, reference being had to the ac companying drawings, forming a part of this specification, in which- Figure 1 represents a side elevation of a Wagonwith a brake applied embodying the improvements in this invention. Fig. 2 is a horizontal view of the same from beneath.

Fig. 3 is an end view from the rear. Fig. 4 is an end view of the same applied to a hayrack. Fig. 5 is an end view of the brakeshoe. Fig. 6 is an end view of a modified form of brake-shoe.

My invention relates to that class of wagonbrakes operating with the back wheels from their rear sides; and consists in the combinations of devices hereinafter set forth and described.

The objeet of this invention is to cause the body, hay-rack, or other equivalent device employed. for holding'the load to receive a portion of the strain necessary to hold the brake-shoe against the wheel, and thereby obviate the necessity of the operator exerting any great pressure on the foot or hand lever to stop the revolving of the wheels.

To enable others skilled in the art to make and use my invention, I will proceed to dethe draw-rod 0, which connects with ahand or foot lever, F, at any suitablepoint above the pivoted end 11 of said foot-lever.

G is a guard in which the free end of the foot or hand lever works, which guard is secured to the body, and is intended to hold the said lever from being thrown outward. H is a spring, secured to the lower side of the body and pressing against the lever E, to hold the same in position when not drawn on, and

' to throw the said bar back when drawn forfront ends connected with the lever E, at about its center of length between the sides of the body, by a pivot, bolt, or equivalent joint-connection.

The brake-shoes M are made with either a square form, as shown in Fig. 5, so as to pre sent four faces, either of which may be used, when the others become worn, by being shifted, or may be made with a triangular form, so as to have three braking-faces capable of operating in the same manner and for the same purpose.

Although the levers or arms J J are pivoted directly to the body A, as shown in Figs. 1 and 3, yet in hay-racks, stone-racks, and equivalent low bodies, the said arms may be pivoted to the body indirectly by any suitable bracket, as shown in Fig. 4, when the same mode of operation may be had and the same result secured.

The manner in which the several parts of this invention operates is as follows: When the driver, with his hand or foot, presses the bar F forward the draw-rod 0 will be made to draw the free end of the lever E forward, when the draw-bars K K will be pulled forward so as to draw on the free ends of the levers J J, pivoted to body A, when the brakebar L will be thrown toward the wheels, to carry the shoes M M against the same, as shown.

It is apparent that by the above-described combination and arrangement of levers and draw-rods with the brake-bar and its shoes, 2. small amount of power may be applied to the hand or foot lever F to effect a great pressure of the shoes on the wheels, while, at the same time, the body is made to support a great amount of the strain exerted.

When any one of the faces of the shoes M becomesworn, some one of the remaining faces J J, brake-bar L, draw-rods K K, and brakemay be turned to face the wheel, to act with shoe M, having three or more faces, substanthe same, which is of great advantage, and tially as described, and for the purpose set obviates the often renewal of the shoes. forth.

Havingdescribedmyinvention, what Iclaim, ROSWELL D. ADAMS. and desire to secure by Letters Patent, is-

The combination, with the lever E, spring H, draw-rod c, and lever F, of the pivoted levers Witnesses:
